The arms 11 are secured to a shaft 6 Figs. 2, 3, and 5, journaled'to the machine-frame A, and the shaft with the arms is reciprocated by a crank b, secured to the shaft b, a connecting-rod b and a crank b on the shaft b.

; stack of boards above the same is lifted in order to clear the lower board from the stack asquickly as possible.-

In the side I) of the receptacle or hopper b is cut a slot b,to provide an exit for the boards or forms. To advance the same toward and between the set of teed-rollersdd, a lever c is trunnioned'in bearings e on the machine-frame A and operated from a cam e on the shaft I), Figs. 2 and 5. 'lhe'cam e and crank I)" are set on the shaft b in such a way that the levcrr is operated upon while the feed-bars 1/ move outwardly in the direction of the arrow, Fig. 5, so that the boardpushed out from the receptacle or hopper b by the bars I) is immediately thereafter pushed between the. feed-rollers (1:41, by the upper end ()l .Ll lever e, which may be provided with a cross-piece as shown in Fig. 4, to insure t'henproper engagement of the,upper end of the lever c with the stoekmg-board.

-Bacl ol' the. set of feed-rollers d this provided a setol' burner-tubcsf and f for the purpose of singeing the fiber fuzz or lint from the surface of the'knit goods stretched over the stocking or other board and forwarded through the feed-rollers (l d. These burnertubesf and f, for which a separate application will be filed, may be of any preferred construction tosuit various requirements, and although we do not claim the burner-tubes and adjuncts shown in the drawings in this application we deem it desirable to describe the same, because of the satisfactory results we have obtained with them. ne of the lmrner-tubesfis shown in Figs. 6 and 7 in de-.

tail. The air-supply pipe is provided with a valvef and an elbow f, in which a gas-- supply pipe f", extending beyond the elbow f is arranged. A valvef regulates the gassupply into the burner-tube, and the latter is supplied with a series of small nozzles through which the gas and air issue, and

to produce a continuous line of even flames shown in Fig. 7.

connecting thesaid nozzles, as particularly The tube f is arranged so that the flame issuing from: the nozzles f and groove f" is directed at a sli ht angle from the vertical downward toward 111's top of the stockingboard,; and the lower tube f is set in advance. of the upper tube so that the flames issuing inan upward direction therefrom do not injure the up er tube f when a board has passed the sai and f. Fron the burner-tubes If and f the board with the stocking passes )etween the rotar brushes and o eratin in'a direcy 9 9 P g tion opposite to that of the feed-rollers d and d and designed to remove the singed and other matter adhering to the surface of the stocking. The gearing and driving mechan-' ism for these brushes, feed-rollers, & c.,' will be described hereinafter. Y

Just back of the brushes 9 and g are j our naled three feed-rollers h, h, and ]L ,th6 two upper rollers h and h of which are adapted to receive the board. from the brushes 9 andg and feed it farther on through another'set of burner-tubes i and i arranged in the same 'nxanner as the tubes f and f and adapted to give a finish to the outer surface of the-stocking. From the feed-rollers 7L. and h the stocking-boards may be fed into and through another set of 'ecd-rollers k andlc to forward the same onto table or movable apron'i or tubes f the upper rollenk may be omitted and thev stocking-board allowed to be c'arried along being in such case assi ted by, the roller is. t

()n'an'extension apf e fra'meA are journaled'two rollers 1 and'r, overwhieh an .end-- less apron i' 'is mounted, the upper surface of this apron traveling in the'direction indicated by an arrow in Fig.2 and adapted to feed the 5 stocking-board deposited on the said apron toward and between the feed-rollers 1c and i It?" for a purpose to be presently described.

'. On the extension a of the machine-frame A may be arranged in any suitable manner an adjustable bumper i for the purpose of checking the travelof the stockingcard beyond the feed-rollers 7c and k, and as long and short 1 stockings are. treated by the machine it is ;de-

sirable to have. an adjustablebum er. This bumper may be of any desired teslgn and shape; In the drawings; however, we have shown a bumper of a simple construction comprising a bracket (1 at each .sideof the ex-. tension (1., These brackets i with braces, are held in holes i 'of a seriesprm'ided in the extension. (1 and may be secured thereto, by thumb-nuts i Figs. 1,2,3, and, 4. Between the brackets it and held thereby are .two rods i Figs. 2 and 4, over which canvas or other cloth is fastened to form the bumper i.

From Fig. 4 it is seen that'the toe end of the stocking and stocking-board. enters all,

from the said nozzles a groove f 'is cut, 1 LllO feed-rollers iirst to prevent the overlapx30 aenere from the board after it leaves the feed-rollers k and it it is brought between theieed-rollers- 70 and k by the apron W, as beforedescribed, and'the stocking-board with stocking is fed by the rollers k andk toward a stripper S,

adapted to remove the stocking from the board and deposit the. former into a basket 3',

stripping.

in the desired direction.

Fig. 2. This stripper S consists of two spring connected flaps s" and s Figs. 8, 9, and 10, which are pivoted at s in the brackets s of the machine-frame A. At the backs of these flaps s and s are provided pins 8, and a spring 8 is connecte pins, so that the flaps are held in normal position, as shown in Fig.9, where the back stops s rest a ainst the edge of one of the brackets s 'lfiie pivots s of the flaps s and s are not on avertical line, for the reason that the stocking on one side of the board should be stripped somewh at in advance of the other sidejvin order to facilitate the operation, of

In stripping the stocking from the board the latter is drawn between the flaps s? and 8,

Figs. Z and 10, by the'action of the feed-roll ers k, k, h, and It? and the fiaps,'owing to the resiliency attained by the spring 8 adjust themselves to the thickness of the board and remove therefrom the stockin juring the latter in' the least ani is deposited in the basket 8; The'board travels on over the idle roller 8* and is guidedby a chute 8 into a receptacle 8}", the sloping bottoms of which causesthe'boardsto be delivered at the side of the machine, where they may be pickedup. and again provided with;

stockings for treatment.

The machine is driven from the main shaft 0, whichimpa'rts rotary motion to the feedroller d, Fig. 3, by the belt 0, the rollers d and dbeing rovided with gear-wheels and c Fi 1.. rdller d by means of pulleys and. belt a", Fig. 4, and as the rollers h and h and it are geared to eachlo'ther, Figs. 1 and 4, they are driven The roller 7c fre ceives motion through the pulleys and belt c from the roller h, and as the rollers k, k, and k are also geared to each other, Figs. 1 and 4-, theyoperate to move the stocking-board in the direction re uired. The apron i is actuated by the rol er i, which is geared to the feed-roller 7c by means of the gear-wheels c, Figs. 3 and 4-, while the brush g is driven by the straight belt a, and the brush g by the crossed belt 0 fipm the pulleys on the shaft (1, Figs. 1 and 4. k

To vary the speed of the machine, coneulleys 0 and e are rovided onthe main shaft C and the shaft 0 the roller d, as shown a in Fi s. 3 and 4. 7

A1 of the top rollers. d, h, and. 7c and the bottom rollers h and k are journaled in slidto the free ends of said I without inthe stocking he roller 72/ is driven from the ing bearing-blockers, Figs; 11 and 12., and springs m are interposed between saidhearing-blocks m and removable caps m sotliat the said rollers will bear upon the rollers d,

h, and ll" ortlie board passing between them yarn-i'uzz;, and other matter, which would soon clogtho extremely fine orificesf The gasentermg through the small pipe]? mitted into the burner-tube f under pressure, which latter may be obtaincdin various ways. The most reliable and preferable means is to provide a'blower p of suitable construction on the machine-frame A and tained.in the room is enerally laden with S into"theburner-tubef mixes with the air adconnect the same to a large pipe 1), closed at p to form a sort of a reservoir. The airis taken in through the pipe 12 and the rotary blower p operated from the main shaft ()"by' pulleys, and the belt 1) keeps the air in the reservoir p under a certain as the machine is in operation.
